Nonidentical Coupling-based N-atom W Entanglement
Ying-Qiao Zhang · Journal of Yanbian University · 2011
Based on the nonidentical coupling of N atoms with a single-mode cavity,a scheme for generation of an N-atom W state is proposed in cavity QED.Under the condition of the large-detuned interaction Δ》gj,the influence of cavity decay is negligible.Such multiple-qubit entanglement will have wide applications to large-scale quantum communication and quantum computation.
